Overview

Gas discharge lamps are a family of artificial light sources that do not generate light by heating a metal filament until it glows white hot (see incandescent lamps). Gas discharge lamps send a electric current through a special gas. Depending on the gas, this generates light directly (most car park and roadway lighting) or the current generates ultra-violet light, which is converted to visible light by fluorsecent powders. The compact fluorescent lamp is perhaps the best known gas discharge lamp. Gas discharge lamps offer long life and high light efficiency. but are more complicated to manufacture, and they require electronics to provide the correct current flow through the gas. Gas discharge lamps have color rendering indexes below 100. In some cases such as the orange low-pressure sodium lamps that are well known as street lighting, the color rendering is so bad that entirely different colors appear the same. This low color rendering index limits the use of gas discharge lamps in homes, shops and restaurants, although careful design will mix incandescent and gas discharge lamps to good effect. See fluorescent lamp for a detailed explanation of a popular version of gas discharge lighting. The incandescent light bulb (archaically known as the electric lamp) uses a glowing wire filament heated to white-hot by electrical resistance, to generate light (a process known as thermal radiation or incandescence). ...

Patent 6150772: Gas discharge lamp controller (5833 words)
A gas discharge lamp controller controls and drives a gas discharge lamp, which may be either a hot cathode lamp or a cold cathode lamp, and may or may not be a fluorescent lamp.
At lower illumination levels, the arc in a gas discharge lamp driven by a conventional ballast undergoes perceivable interruptions that cause the lamp to appear to "flicker." A lamp is considered not to be in normal operation when it is flickering.
The breakdown voltage is the peak-to-peak measurement of the breakdown voltage of lamp 12 for the indicated brightness.
